A Specification of Letters Patent.

Application medseptember 2, 19114. seal No. 859,869.

To all whom t may concern.

Be it kno-wny that I, ELLswoR'rH TILDEN,

a citizen of the United States, residing at A'sotin, in the county of Asotin and State of 5' Washington, have invented certain new and useful Improvements in Stump-Burners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled inthe art to which it appertains to make and use the same.

This invention relates to new and useful improvements in stump burners and has for its principal object to provide a device' which will effectively direct fiame of fire against a stump to destroy the same.

Another object of the invention is to provide a portable device which may be easily and quickly attached to a stump to perform the above function, and which may be easily 'and quickly transported and set up forl use.

With these and other objects in view, the invention consists in the combination and arrangement of parts which will be fully set forth in the following specification and in the accompanying drawing, in which:

Figure 1 is a sectional view of a stump showing this improved stump burner as it wouldappear when applied thereto. Fig. 2 is a rear view in elevation o-f the stump burner, and Fig. 3 is a sectional view taken on line 3 3 of F ig. 1. Referring now to the drawings by characters of reference, the numeral 1 designates the stump which is first prepared by drilling or boring the hole 2 therein, a suitable smoke conveying pipe 3 is inserted in one i 'end of the hole and carries at its oppo-site terminal the elbow 4 which is arranged to communicate with the pipe 5 which is upturned to cause the proper draft through th stump. cperating with the mechanism hereinbefore referred to is the fire box designated l5 as an entirety by the numeral 6 which cornprises the cylindrical body 7 having formed at one end the closure 8 which is formed with the outlet aperture 9. A suitable smoke pipe 10 is secured to the end wall 8 and ar- 0 ranged to register with the outlet opening 9, and this pipe 10 has secured thereto the short length of pipe 11 carrying the flange 12 which is arranged to bev inserted. in the stump in such a manner that the flange 12 5 will limit the inward movement of the pipe. The end wall 13 of the burner is prospaced. interval from vided with the fuel door 14 having formed thereon the draft controlling device 15, by means of which the amount of air permitted to enter the burner is controlled. -A suitable partition wall 16 is secured within the cylindrical body 7 near the opening 9, and this wall is cut-away at its upper edge as at 17 to permit the ho-t gases from the interior of the cylindrical body 7 to pass into the pipe 9 and from thence into the stump.

It will be apparent from the foregoing, that in use the stump is drilled as illustrated in the drawing and the short length ll of pipe is then inserted in the aperture as shown. The pipe 10 is then connected to the pipe 11, and it will thus be seen that communication will be formed between the burner 6 and the aperture`2 in the st-ump. The opposite terminal of the aperture has pressed thereinto the pipe 3 which is constructed so that it communicateswith the pipe 5 and thereby creates a draft through the burner 6 and stump l, thereby drawing the fire and the heat from the burner into the stump and destroying the same. The device is then ready tol be set in operation, and it will be apparent that the heat and fire from the burner will be drawn through the stump, thereby causing the same to be completely demolished.

While in the foregoing there has been shown anddescribed the preferred embodiment of this invention, it is to be understood that such changes in the combination and arrangement of parts as may fall within the scope of the claims may be resorted to without departing from the spirit and scope of the invention. Y

Having thus described the invention, what is claimed as new, is

l. A stump burner furnace comprising a cylindrical body adapted to receive inflammable material, a front wall secured to the body havin a draft opening, a rear wall secured to t e body and provided with an outlet aperture, a partition wall secured within the lower part of the said body at a and extending to a point above the outlet aperture to prevent the said inflammable material from clogging the outlet aperture, a pipe secured to said outlet aperture to direct the flame and gas from the body'into a stump which is to be burned.

2. The combination with a stump having been previously prepared by drilling an ivoo ' furnace comprising a cured to the body, said yfront wall being Q provided with a draft opening, a rear wall secured to the body, said rear Wall being provided with an outlet aperture, a partil'tion wall secured within, the lower part vof said body at a spaced interval from and extending to a point above said outlet aperture to prevent the inflammable material from clogging said outlet aperture, a pipe connected to said outlet aperture, the opposite end of said pipe eztztendin into the aperture in the stump' and av'dra t pipe ex. 15

tending into the opposite end of the aperture in the stump, said draft pipe being arranged to cause a draft through the stump W- t0 draw the fire from the furnace into the stump" thereby destroying the same. 20 In testimony whereof I aiix my signature in presence of two '.witnesses.
